JPSS-2, or Joint Polar Satellite System-2, is the second of the United States National Oceanic and Atmospheric Administration (NOAA)'s latest generation of U.S. polar-orbiting, non-geosynchronous, environmental satellites called the Joint Polar Satellite System. JPSS-2 was launched on 10 November 2022 [1] and join NOAA-20 and Suomi NPP in the same orbit. [2] Circling the Earth from pole-to-pole, it will cross the equator about 14 times daily, providing full global coverage twice a day. [3]

Contents

JPSS-2 will provide operational continuity of satellite-based observations and products for NOAA Polar-Orbiting Environmental Satellites (POES) and Suomi NPP satellite and ground systems. [3] The baseline plan for JPSS Ground System will be sustained to support JPSS-2, similar to NOAA-20. The JPSS-2 spacecraft will host the following instruments: 1) VIIRS, 2) CrIS, 3) ATMS, and 4) OMPS. It was at one time intended to carry the Radiation Budget Instrument (RBI) but NASA cancelled that project in 2018. [4]

Development

On 24 March 2015, NASA announced that Orbital ATK would build one, and possibly three, Joint Polar Satellite System spacecraft. In winning the contract, Orbital unseated the incumbent Ball Aerospace & Technologies which had built NOAA-20 (JPSS-1) and Suomi NPP. [5] JPSS-2 is based on Orbital ATK's LEOStar-3 spacecraft bus platform, which was also used on Landsat 8. The second Ice, Cloud and Land Elevation satellite (ICESat-2) and the Landsat 9 spacecraft are also based on the LEOStar-3 and are being built at Orbital ATK's Gilbert facility at the same time. [6]

The launch services contract was awarded to United Launch Alliance (ULA) on 3 March 2017. [7]

Launch

JPSS-2 was launched on 10 November 2022 on an Atlas V 401 rocket from Vandenberg Space Launch Complex 3 (SLC-3E) at Vandenberg Space Force Base in California. It was the final launch of an Atlas V from Vandenberg Space Force Base. [1]

JPSS-2's launch day had been pushed back a couple of times. In May of 2022 it slipped a little more than a month when VIIRS experienced a test equipment anomaly during thermal vacuum (TVAC) testing. [8] It slipped again from November 1st following ULA discovering that the battery on the Atlas V's Centaur upper stage needed to be replaced. [9] Launch and activation was hampered by a solar array deployment failure that was detected a few hours after launch. [10]

Instruments

The JPSS-2 sensors/instruments are: [3]

Advanced Technology Microwave Sounder (ATMS)

The Advanced Technology Microwave Sounder (ATMS) is a cross-track scanner with 22 channels. It provides sounding observations needed to retrieve atmospheric moisture and temperature profiles for real-time civilian weather forecasting and to provide continuity of these measurements for climate monitoring. It is a lighter-weight version of the previous Advanced Microwave Sounding Unit (AMSU) and Microwave Humidity Sounder (MHS) instruments flown on previous NOAA and NASA satellites with no new performance capabilities. [11]

Cross-track Infrared Sounder (CrIS)

The Cross-track Infrared Sounder (CrIS) instrument will be used to produce high-resolution, three-dimensional moisture, pressure, and temperature profiles. These profiles will help scientists to enhance weather forecasting models, and will be used in both short- and long-term weather forecasting. They will help improve the understanding of regular climate phenomena such as El Niño and La Niña. This is a brand-new instrument with breakthrough performance. [12] CrIS represents a significant enhancement over NOAA's legacy infrared sounder — High Resolution Infrared Radiation Sounder (HIRS) and is meant to be a counterpart to the Infrared Atmospheric Sounding Interferometer (IASI).

Ozone Mapping and Profiler Suite (OMPS)

The Ozone Mapping and Profiler Suite (OMPS) is a suite of three hyperspectral instruments that is extending the 25-plus year total-ozone and ozone-profile records. Ozone-assessment researchers and policy makers use these records to track the health of the ozone layer. Better testing and monitoring of the complex chemistry involved in ozone destruction near the troposphere is made possible by the improved vertical resolution of OMPS data products. OMPS products, when used with cloud predictions, also produce better ultraviolet index forecasts. [13] OMPS carries on a long tradition of space borne measurements of ozone beginning in 1970 with the Nimbus 4 satellite and continuing with the Solar Backscatter Ultraviolet (SBUV and SBUV/2), Total Ozone Mapping Spectrometer (TOMS) and Ozone Monitoring Instrument (OMI) instruments on various NASA, NOAA, and international satellites. Over the more than 30-year period in which these instruments have been operating, they have provided a very detailed and important long-term record of the global distribution of ozone. [14]

Visible Infrared Imaging Radiometer Suite (VIIRS)

The Visible Infrared Imaging Radiometer Suite (VIIRS) takes global visible and infrared observations of land, ocean, and atmosphere parameters at high temporal resolution. Developed from the Moderate Resolution Imaging Spectroradiometer (MODIS) instrument flown on the Aqua and Terra Earth Observing System (EOS) satellites, it has significantly better performance than the Advanced very-high-resolution radiometer (AVHRR) previously flown on NOAA satellites. [15] VIIRS Focal Planes were manufactured by Raytheon Vision Systems in Santa Barbara, CA

Discontinued instruments

Radiation Budget Instrument (RBI)

The Radiation Budget Instrument (RBI) was a planned scanning radiometer capable of measuring Earth's reflected sunlight and emitted thermal radiation. RBI was to fly on JPSS-2, but it experienced significant technical issues and substantial cost growth. Because of these challenges, and the low risk of experiencing a gap in this data record due to having two relatively new instruments in orbit at the time, NASA decided to discontinue development of RBI. [4] RBI struggled from the beginning. It was originally to be on NOAA's proposed Polar Free Flyer satellite, but in 2014, Congress, led by its Republican majority, refused to fund the satellite. After moving the instrument to JPSS-2 and awarding the contract for development in June 2014, [16] NASA almost immediately began the process of dropping the sensor. NASA halted development in 2015 citing cost and technical concerns. [17] In 2017, it was defunded in the Trump administration's first budget because of "schedule and technical difficulties". [18] RBI got a brief reprieve when the Senate stated that if NASA determined that RBI could be ready for inclusion on the Joint Polar Satellite System 2 (JPSS-2) spacecraft and stay within budget it could continue with reprogrammed funding. [19] But on 26 January 2018, NASA announced their intention to discontinue development of RBI and shortly thereafter it was again left unfunded in the Trump administration's FY 2019 budget. [4] [20]
